My experience: ask you assembly house. The guys I work with us the fiducial in the bottom right as the zero, and rotations CCW.
One issue (big issue) is that components have varying rotations in the reels, so assembly houses prefer to confirm the rotations against a prototype board. IPC-7531 tries to address this, but I don't know how consistent manufacturers are. -- Turn ideas into products - http://www.engineersimplicity.com The Art of Engineering - http://blog.engineersimplicity.com _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
